When I started this, I have the kids apply for the position first. Then had the class vote on who they thought would make the best candidate (google form). We had the Hs officers come in and talk to them before so they knew who they were and saw an example of the band program and knew they were working together to make it better. Plus recruitment. They were held accountable for the position by weekly/monthly meetings with me (director). But the officers I used were Band President, Social Media Officer (made monthly events for the band), and Librarian.
